,CARPET-SWEEPER.

SPECIFICATION forming part of Letters Patent No. 523,339, dated July 24,1894.

Applic i n file November 17, 1893- Serial No. 491,281 (No model.)

- carpet sweepers, and its object is to provide the same with certainnew and useful features, hereinafter more fully described andparticularly pointed out in the claims, reference being had to theaccompanying drawings, in which I Figure 1 is an end elevation of adevice 6111- bodying my invention with parts broken away to show theconstruction; and Fig. 2 a plan view'of one end of the same with thecase in horizontal section.

Like letters refer to like parts in both of the figures. r

A represents the case supported upon two larger drive wheels B, and twosmaller trailing wheels B, one of each only, being shown in thedrawings. In the forward part of said case and near the bottom of thesame is the dust pan E, which is pivoted near its forward side at E, tosaid case, being vertically movable at its rear side and provided nearits rear corners with pins or studs F, which project outwardly throughvertically elongated slots A in the end walls of the case, and engagethe horizontal arms D of bell crank levers pivoted to the case, saidlevers having upwardly projecting arms D, in which is journaled thebrush shaft 0, having pulleys O at each end adapted to engage thedriving wheels B and rotate said brush shaft as said arms D'are pressedforward by the bail G, which is pivoted at its respective ends to theupper ends of said arms. A vertical slot A in the end walls of the casereceives said brush shaft and permits its upward removal from said casethrough a door J in the same, or said door may be opened and the brushexamined, or cleaned, without inverting the case; an inclined front adoor K over the dust pan E is provided through which the contents ofsaid pan may beremoved. A guard bar H extends outside of the pulleys andbell crank described, which furnishes a support for the outer ends ofthe pivots and journals of the same, and also serves asa fenderforthedevice. Said bar is attached to and supported in place-by studs I I,projecting from the end wall of the case.

From the foregoing, the operation of my device may be readilyunderstood. Upon the forward stroke, the arms D are pressed forward anddownward in a diagonal direction, thus lowering the brush in closercontact with the carpet and forcing the pulley C in operative contactwith the drive Wheels B, and'at the same time lowering the rear edge ofthe dust pan in close contact with the carpet to I prevent dust frompassing below said pan. At the same time if any bulky obstruction passesbeneath the same, the pins F will be free to rise in the slots A, andthus permit the rear of said pan to rise and pass over said obstruction.Upon the backward stroke, the arms D are drawn diagonally backward andupward thus removing the brush from contact with the carpet and thepulleys C from contact with the wheels B, and at the same time liftingthe rear edge of the dust pan clear of the carpet, whereby the deviceruns freely backward,I thus secure a very cheap and effective device.

What I claim is 1. In a carpet sweeper, in combination with a drivewheel journaled on the case, and a dust pan pivoted to the case near oneside, and vertically movable at the other side, a bell crank leverpivoted to said case having one arm supporting the movable side of saiddust pan, a brush shaft journaled in the other arm of said bell cranklever, and having pulleys engaging said drive wheels, and a bail pivotedto said arm, substantially as described.

2. In a carpet sweeper, a case having vertically elongated openings nearthe bottom of brush shaft journaled in said levers and having pulleysengaging said wheels, and a bail pivoted to said levers, substantiallyas described.

In testimony whereof I aflix my signature in presence of two Witnesses.

GEORGE I-I. GERE.
